Embodiment 1

[0033] The first embodiment provides a cavity filter, which includes a filter cavity and a cover plate 3 arranged on the filter cavity. The cover plate 3 is provided with a tuning screw 5, and the tuning screw 5 is installed by a nut 6 On the cover plate 3, the nut 6 includes a nut body, the nut body is provided with a through internal threaded hole 9, and the end surface of the nut body is evenly distributed with at least two recesses for rotating the nut with an external tool. groove.

[0034] Such as Figure 6 to 8 As shown, the groove provided on the end surface of the nut body extends radially outward and communicates with the external space. The groove is opened on the periphery of the nut body, that is, on the outer circumference of the end surface of the nut body, there is a groove that opens outward, which does not affect the internal threaded hole, so that the nut does not need to be made thick. It can be a normal standard thickness, or it can be made into a thin nut. ...

Embodiment approach

[0040] In another embodiment, the groove is located between the inner threaded hole wall and the outer wall of the nut body. The groove is opened on the end surface of the nut body, and is supported by the inner threaded hole wall and the outer wall on both sides in the radial direction, which will increase the strength of the entire nut.

[0041] The number of the grooves can be 2 to 12, evenly distributed on the end surface of the nut body, preferably 6 grooves.

[0042] The grooves can be distributed at one end of the nut main body or the other end of the nut main body, that is, grooves are distributed on the upper and lower end surfaces of the nut main body.

[0043] The nut can be hexagonal, quadrangular or round, preferably round, and the use of a round shape can save more space between the nuts.

[0044] The nut of the present invention is arranged on the cavity filter. By setting grooves on the end face of the nut, the outer diameter of the wrench that matches the nut can be m...

Embodiment 2

[0046] The second embodiment provides a cavity filter cover plate, the cover plate is provided with a tuning screw, the tuning screw is installed on the cover plate through a nut, the nut includes a nut body, and the nut body is provided with a through hole At least two grooves for rotating the nut with external tools are evenly distributed on the end surface of the nut body.

[0047] The groove provided on the end surface of the nut main body extends radially outward and communicates with the external space. The groove is opened on the periphery of the nut body, that is, on the outer circumference of the end surface of the nut body, there is a groove that opens outward, which does not affect the internal threaded hole, so that the nut does not need to be made thick. It can be a normal standard thickness, or it can be made into a thin nut.

[0048] The number of the grooves can be 2 to 12, evenly distributed on the end surface of the nut body, preferably 6 grooves.

[0049] The gro...

Abstract

The invention discloses a nut, a cavity filter cover plate, and a cavity filter. The cavity filter comprises a filter cavity and a cover plate arranged on the filter cavity. The cover plate is provided with a tuning screw; the tuning screw is installed on the cover plate through a nut; the nut comprises a nut main body; the nut main body is provided with a penetrating internal threaded hole; and at least two grooves for cooperating with an external tool to rotate the nut are uniformly distributed on the end surface of the nut main body. According to the invention, the at least two grooves for cooperating with the external tool to rotate the nut are uniformly distributed on the end surface of the nut main body so that the nut can be used in case of small space, the nut is applied to the cavity filter cover plate or the cavity filter, tight arrangement can be realized by use of threaded connection, nuts are not deadlocked with each other as long as a quite small gap is arranged between neighboring nuts, and it is unnecessary to specifically leave quite large space at the circumferences of the nuts.

Description

Technical field [0001] The invention relates to a nut, a cavity filter cover plate and a cavity filter. Background technique [0002] Such as figure 1 As shown, a cavity filter cover plate 3 is provided with tuning screws, and the tuning screws are respectively mounted on the filter cover plate 3 through a first hex nut 1 and a second hex nut 4, and a hex nut wrench 2 can be used to tighten the first hex nut 1 and the second hex nut 4 to fix the tuning screw on the filter cover, the hex nut wrench such as figure 2 As shown, when using a hexagon nut wrench to install or remove a hexagon nut, put the hexagon nut wrench on the hexagon nut, make the six sides of the wrench and the six sides of the hexagon nut mesh with each other, and turn the wrench to remove or fix the hexagon nut. [0003] In the process of research and practice of the prior art, the inventor of the present invention found that the wrench used in the prior nut would occupy a certain space when sleeved on the hexago...
